A developer named Reald did make a big font version with SWR display about 4 or 5 years ago and you could try that out and see if it works for you. The links are in archive posts. A simplified menu be

Yes it is the transmission line that has the standing waves on it. However as I stated in my previous post the transmitter power amplifier is designed for a specific load which is 50 ohms for ham tran

Bottom right hand corner of menu indicates it is for Hugen’s (Zeenko) -H and -H4 with older version 1.1 firmware by DiSlord

Nizar, Are you trying to use 75 ohm coax with a transmitter designed for 50 ohm? If so you should be not be using the DiSlord impedance setting which changes the system impedance to 75 (or 77) ohms. Y

The resonant frequency of an antenna and the frequency where the SWR is the minimum are different. Resonance occurs when the reactance X = 0 at the antenna feedpoint. When you measure the SWR at the t

JimLS, Did you get what you need from all the posts on this topic? Roger

You need to set your traces to read R and X. You have to go into the Display Menu and select a Trace and set it to S11. Then go back and set the Format to Resistance or Reactance. Then set the Scale t

In order to make a measurement of an inductor's parameters like inductance, reactance and resistance vs frequency and self-resonant frequency the easiest method is the S11 shunt method using just CH0

The reactance can be much less than 50 ohms and much greater than 50 ohms and you will still get good results. Here is a measurement of an inductor that measured 9.8 uH at 100 kHz. on a DE-5000 LCR me

Erik has nothing to do with VNA products - he manufactures the tinySA... Th OP has a product which is an owocomm design.

You can't just swap in a larger screen because it will not be pin compatible. If you own a 2.8" you could buy a 4" model which is much easier to read. Or you can connect it to your PC using NanoVNA Sa

Take the battery out and run it on USB power. Roger

Carlos, I suggest you always search the archives for old posts on a subject. Often you will find the topic has been discussed before (often at great length). Here is one that will interest you. ... ht

Those gold ones have horrible performance. If you cut one open you will find a leaded resistor inside with one long lead that just brushes against the connector. You will get rising resistance with fr

You don't get any benefit doing this and you add another component that has parameters (R and X) that change with frequency and need to be subtracted from the results to get the values for the inducto

The typical NanoVNA only measures the phase of the reflection coefficient (S11) which is NOT the same as impedance phase. Recent firmware from DiSlord also calculates the impedance phase angle and you

This group has been around for 5 years now and you will find lots of informative discussion on many topics in the archives which you can easily search. About 2 years ago we had a long discussion on me

Not all SD cards work with the H4 due to the way the firmware is implemented. I use a 32 GB Kingston card and it works fine. You just have to try a few brands to get one that works for you Roger

The distance between the center and any point on the Smith chart is the magnitude of the reflection coefficient known as Gamma. Abbreviated as |S11| or |Γ|. The angle from the horizontal line to this
